An administrator is reviewing a vSphere Distributed Resource Scheduler (DRS) enabled Cluster and observes unexpected behavior as shown in the Exhibit.

What are three potential causes of the cluster imbalance? (Choose three.)

A local device is mounted to one or more virtual machines.

DRS rules prevent virtual machines from being moved.

vMotion is not configured and enabled.

There are insufficient cluster resources to perform the migration.

DRS has been configured for a conservative migration threshold.

Answer: A,B,C Explanation:

Cluster imbalance is often caused by a local device mounted to one or more VMs and the DRS rules are preventing the VMs from being moved. Similarly, check vMotion to see if it is configured and enabled.

Which condition would cause a vCenter Server installation to fail when installing on a Windows virtual machine?

The virtual machine does not have at least four vCPUs.

The virtual machine is running Windows Server 2008.

The virtual machine has an E1000 network device.

The virtual machine does not have 16GB of RAM.

Answer: B Explanation:

If you use Simple Install to install vCenter Server and components on a Windows Server 2008 R2 or Windows 2012 host, and the host is configured to use DHCP IP addressing, the installation fails with warning and error messages.
